makestuff / HOWTO

Running blinky demo on Spartan-3AN

	First, add these two lines to /etc/udev/rules.d/10-local.rules (create the file if it doesn't
	already exist):

	ACTION=="add", SUBSYSTEM=="usb", ATTR{idVendor}=="03eb", ATTR{idProduct}=="2ffa", GROUP="users", MODE="0660"
	ACTION=="add", SUBSYSTEM=="usb", ATTR{idVendor}=="1d50", ATTR{idProduct}=="602b", GROUP="users", MODE="0660"

	...so you can talk to the relevant USB devices without sudo. Then connect your JTAG port to
	your Minimus (TDO->PB3, TDI->PB2, TCK->PB1, TMS->PB0, +3.3V->VCC and GND->GND - keep the
	connections short), and power up the board. No need to connect the USB cable to the FPGA board,
	just the Minimus.
